Xya qhov ntsuas los txiav txim qhov zoo ntawm cov khoom siv suab zoo
Tam sim no tus nqi lag luam ntawm cov khoom siv suab nrov tau ya thoob plaws lub ntuj, xws li los ntawm ob peb kaum ntawm yuan mus txog li kaum tawm txhiab yuan, yog li yuav ua li cas xaiv tus hais lus uas haum rau koj? Ntau tus neeg xav tias kim yog tsim nyog, tab sis nws tsis yog.
Cov kev tsis sib xws ntawm cov khoom siv suab nrov tuaj yeem piav qhia los ntawm cov khoom siv suab nrov, cov lus teb ntau zaus, rhiab heev, lub zog, teeb liab-rau-nruab piv, distortion, thiab impedance.
01
suab tshuab
Kho vajtse 3D suab teebmeem technologies muaj ntau niaj hnub no, xws li SRS, APX, Q-SOUND thiab Virtaul Dolby. feem ntau.
02
Ntau zaus
Feem ntau, cov lus teb ntau zaus hauv cov khoom siv suab nrov yog qhov ntau zaus thiab cov lus teb ntau zaus. Tus qub yog hais txog qhov sib txawv ntawm qhov qis tshaj qhov ua tau zoo tshaj plaws thiab qhov ua tau zoo tshaj plaws ntawm kev ua haujlwm ntawm tus hais lus; tom kawg yog hais txog lub suab zaus tso zis ntawm qhov tsis tu ncua voltage. Thaum lub teeb liab txuas nrog lub system. Qhov kev qhia no yog qhov tseem ceeb rau kev soj ntsuam kev ua tau zoo ntawm tus neeg hais lus, thiab nws muaj feem cuam tshuam ncaj qha rau kev ua haujlwm thiab tus nqi ntawm tus neeg hais lus, yog li koj yuav tsum tau them nyiaj tshwj xeeb thaum yuav tus hais lus, tab sis tam sim no ntau lub tuam txhab muaj cov ntawv cuav, yog li koj tseem yuav tau mloog qhov tseeb, thiab ceev faj.
03
zog
Lub hwj chim tsis nyob rau hauv cov khoom siv suab nrov kuj yog qhov tsis meej pem. Lub hwj chim feem ntau yog hais txog lub suab ntawm tus neeg hais lus muaj zog npaum li cas. Muaj ob daim ntawv lo rau lub zog no, ntsuas lub zog thiab siab tshaj plaws tiv thaiv lub zog (lub zog tam sim lossis lub zog siab PMPO). Kuv yuav tsis piav qhov no kom ntxaws. Koj tuaj yeem nrhiav tau los ntawm kev tshawb nrhiav. Raws li ib txwm muaj, txhawm rau ua kom tau raws li cov neeg siv khoom xav tau, cov lag luam feem ntau tau teeb tsa lub suab paj nruag siab, yog li thaum yuav cov neeg hais lus multimedia, lub zog ntsuas yuav tsum yeej. Kuv xav piav qhia ntawm no tias tsis yog lub zog loj dua, qhov zoo dua, tab sis qhov haum yog qhov zoo tshaj plaws, thiab nws suav nrog hauv cheeb tsam.
04
rhiab heev
Qhov rhiab heev ntawm cov khoom siv suab yog hais txog lub suab siab ntsuas ntawm qhov chaw ib 'meter' nyob rau hauv pem hauv ntej ntawm ntsug axis ntawm lub dav hlau hais lus thaum lub teeb liab 1W / 1kHz nkag mus rau tus hais lus input davhlau ya nyob twg. rhiab heev yog ntsuas nyob rau hauv decibels (DB). Rau txhua txhua 3dB qhov sib txawv ntawm tus neeg hais lus rhiab heev, cov zis suab siab yuav ob npaug. Qhov rhiab heev ntawm cov neeg hais lus zoo tib yam yog nyob rau hauv thaj tsam ntawm 85-90dB, qis rhiab heev hauv qab 85dB, thiab siab rhiab heev tshaj 90dB. Feem ntau, qhov rhiab heev ntawm cov neeg hais lus multimedia yog qis dua me ntsis.
05
impedance
Lub impedance Performance index nyob rau hauv cov khoom siv suab hais txog qhov piv ntawm qhov voltage rau tam sim no ntawm lub teeb liab input. Lub tswv yim impedance ntawm tus hais lus feem ntau muab faib ua ob hom: siab impedance thiab qis impedance. Feem ntau, cov input impedance siab tshaj 16 ohms yog siab impedance, thiab input impedance qis dua 8 ohms yog tsawg impedance. Tus qauv impedance ntawm tus hais lus yog 8 ohms. Lub npe impedance ntawm cov neeg hais lus hauv khw yog 4 ohms, 5 ohms, 6 ohms, 8 ohms, thiab 16 ohms. Txawm hais tias qhov ntsuas no tsis muaj dab tsi cuam tshuam nrog kev ua haujlwm ntawm cov neeg hais lus, nws yog qhov zoo tshaj kom tsis txhob yuav cov neeg hais lus qis. Tus nqi pom zoo yog tus qauv. 8 ohms, qhov no yog vim hais tias nyob rau hauv cov ntaub ntawv ntawm tib lub hwj chim amplifier thiab tso zis hwj chim, cov neeg hais lus impedance tsawg tuaj yeem tau txais lub zog tso zis ntau dua, tab sis yog tias qhov impedance qis dhau, nws yuav ua rau qis qis thiab bass degradation.
06
SNR
Lub teeb liab-rau-nruab nrab qhov ntsuas ntsuas hauv cov khoom siv suab nrov feem ntau yog hais txog qhov sib piv ntawm lub suab nrov ib txwm ua si rov qab los ntawm tus neeg hais lus rau lub suab nrov. Lub teeb liab-rau-suab nrov piv yog tsawg, thiab lub suab nrov yog qhov hnyav thaum lub teeb liab me me nkag. Lub suab nyob rau hauv tag nrho cov ntau dhau los ua av nkos thiab tsis meej, thiab nws tsis paub tias lub suab twg raug tso tawm, uas cuam tshuam rau lub suab zoo. Nws raug nquahu kom tsis txhob yuav cov neeg hais lus nrog lub teeb liab-rau-lub suab qis qis dua 80dB (xws li subwoofers qis dua 60dB).
Qhov ntsuas no yog hais txog qhov piv ntawm lub suab nrov ib txwm ua si rov qab los ntawm tus neeg hais lus rau lub suab nrov. Lub teeb liab-rau-suab nrov piv yog tsawg, thiab lub suab nrov yog qhov hnyav thaum lub teeb liab me me nkag. Ntawm no, nws raug pom zoo kom tsis txhob yuav cov neeg hais lus nrog lub teeb liab-rau-lub suab qis qis dua 80dB (xws li subwoofers qis dua 60dB).
07
Distortion
Lub ntsiab lus ntawm distortion nyob rau hauv cov khoom siv suab yog yeej ib yam li cov amplifier. Qhov txawv yog hais tias lub input ntawm lub amplifier yog ib tug hluav taws xob teeb liab, thiab cov zis yog tseem ib tug hluav taws xob teeb liab, thaum lub input ntawm tus hais lus yog ib tug hluav taws xob teeb liab, thiab cov zis yog lub suab yoj teeb liab. Yog li qhov distortion ntawm tus neeg hais lus hais txog qhov distortion ntawm electro-acoustic teeb liab hloov dua siab tshiab. Qhov kev tso cai ntawm lub suab yoj distortion yog nyob rau hauv 10%, thiab tib neeg pob ntseg tsis hnov tsw rau distortion li ntawm 5%. Nws yog qhov zoo tshaj kom tsis txhob yuav cov neeg hais lus nrog tus nqi distortion ntau dua 5%.
